From the posix bag of goodies, you might also try FOLD.

:FOLD.HPBIN.SYS "-bs -w80 INFILE" >> OUTFILE

FOLD is also useful in CGI scripts. 
Omit the s if you do not want to break at spaces.

greetings
posix might be your friend - specifically OD.HPBIN.SYS with the -j and -N flags.
as in (should of course be wrapped in a nice script):
:OD.HPBIN.SYS "-N80 FILE"
:OD.HPBIN.SYS "-j 80 -N80 FILE"
:OD.HPBIN.SYS "-j 160 -N80 FILE"
...etc...
